Invar Barcode Levelling Staff 3 m
3 m铟钢条码水准尺
Sub-millimetre digital levelling depends on a staff whose length does not change with temperature. This 3 m one-piece staff carries an invar barcode strip under constant spring tension, expanding no more than 1 × 10⁻⁶ /°C, with code accuracy of ±0.02 mm per metre. An aluminium frame, handles and 10′ bubble keep it stable.
